NORTON M. DENEGAR, OF HUDSON, NEW YORK.

SHAPER-MACHINE.

Application filed November 13, 1911.

To all whom t may concern:

Be it known that I, NORTON M. DENEGAR, a citizen of the United States, residing at Hudson, in the county of Columbia and State of New York, have invented certain new and useful Improvements in Shaper- Machines, of which the'following is a specification.

My invention relates to wood-working machines and the Object of my invention is to provide a counter-balance for shaping machines so that one knife only may be used for special work. I accomplish this object by means of the mechanism illustrated in the accompanying drawings in which- Figure 1 is a perspective view of a shaper and my counter-balance mounted thereon. Fig. 2 is a perspective view of my counterbalance collar. Fig. 3 represents views of different weights used with my counter-balance collar.

Similar letters refer to similar parts throughout the several views.

It is well known that in working up odd designs and unusual shapes from wood cutter-knives have to be made for each special design or shape. The spindle carrying these knives revolves very rapidlyand usually as high as live thousand. revolutions a minute. In order that the spindle shall run smoothly without vibration it is usual to make two knives exactly alike and exactly the same shape, size and'weight, one for each side of the spindle in order not to disturb the motion.

My invention consists of making a collar of the same general design as the collars which hold the knives in place but with holes in the surface and mount it upon the spindle above the collars'holding the knives. Then in the holes in this counter-balance collar weights are placed to counter-balance the weight of the knives or the difference between the weights of the knives or the difference between the weight of the knife and a blank.

Referring to the drawings, A represents a table of the usual form.

B represents the spindle extending through the table and to which the cutter knives are attached. The power is applied to the spindle in the usual way below the surface of the table.

C is a collar xedly attached to the spindle B. On top of this collar is placed the cutter-knife E. D is a collar placed above the Specification of Letters Patent.

cutter knife to hold the cutter-knife fixedly and firmly in position. These collars C and I) are of the usual style and construction used for that purpose.

E is a cutter-knife of any style necessaryL to make the desired pattern. The cutterknife E is held between the collars C and D in the usual way.

F is a counter-balancing collar placed on the spindle above the collar D.

G, Gr, are holes in the collar F adapted to receive the counter-balancing weights.

H, H are weights adapted to fit in the holes G in the collar F. These weights are of different sizes so as to counter-balance the weights of the different knives.

In use a single knife is made of the type and style desired. This knife is put in a balance and the weights H, I-I are put upon the other side until the weights exactly balance the knife to be used. The knife is secured in position and the counter-balancing collar adjusted upon the spindle above the top collar holding the knife, the row of holes in the counter-balancing collar being arranged on the side of the spindle opposite the knife. Then weights H, H of proper weight with the blank if one is used to counter-balance the cutter are placed in the holes. If the knife extends any appreciable distance beyond the periphery of the collar the weights are placed in the outside holes in the collar but if the knife is short the weights are placed nearer the center.

Constructed in this way only one knife is necessary to do any particular work and any sizes of weights may be used necessary to exactly counter-balance the weight of the knife and thus much time is saved from lar job.

What I claim as my invention and desire holes, a cutter-knife and means for holding said cutter-knife upon Said spindle.

3. In a shaping machine a spindle, collars mounted upon said spindle adapted to hold a cutter-knife, a cutter-knife mounted upon said spindle between said holding collars7 a counter-balancing collar mounted upon said spindle above the holding collars, holes in the upper surface of said counter-balancing collar adapted to receive weights, weights of different sizes adapted to occupy the holes in said counter-balancing collar whereby the weight of the single knife may be held between said holdin collars and balance by the weights in sai counter-bah ancing collar, substantially as described.

In testimony whereof I alix my signature in presence of two witnesses.
